Over the past century, the Catholic Church as an institutional entity has had a complex, and often contentious, relationship to racial politics. Given its history in colonialism, role in domestic slavery and the widely publicized complicity during the Holocaust, racism is something that has deep seated roots within the Church hierarchy.
That said, over the past fifty years, the Catholic Church, both internationally and in the U.S., has begun to confront racism as a moral issue.
